2,103,843 VENTILATR Melanie Filion, ne Le comme, Montral, Quebec, Canada ,Application March Z7, 1336s Serial o. 1 claim. (ci. tje-2i The present invention relates to improvements in `ventilator apparatus 'particularly adapted for enclosed body automobiles and the like.

An object of the inventionv is the provision of Ventilating apparatus which is very efficient for expelling foul air from'a chamber, as for instance the interior of an automobile body.

Another object of the invention is the provision of a ventilator which will be efficient and reliable in operation.

A further object of the invention is the provision of a ventilator of the aforesaid character which is relatively simple and durable in construction.

?,5 Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate correspending parts throughout the same: n

Figure 1 is a longitudinal section through a closed body automobile equipped with the ventilator, l Y

Figure 2 is a fragmentary transverse sectional view through the same,

Figure 3 is a bottom elevational view of the ventilator installed in a vehicle,

Figure 4 is a section taken on the line 4-4 of Figure 3,

Figure 5 is a top plan View with the top cover plate removed, and Y Figure 6 is a fragmentary section taken on line 6-6 of Figure 4.

35 Referring to the drawing, wherein for the purpose ofY illustration is shown a preferred embodiment of the invention, I0 generally designates a conventional form of automobile of the enclosed sedan type. My improved ventilator is to be 40 mounted within the central top portion of the vehicle body for expelling foul or stagnant air from the interior thereof.

The ventilator embodies an exterior shell having a solid annular wall forming body I2 closed 45 at the top by means of a rectangular shaped top plate I3 secured on the annular wall section I2 by screws I4. The bottom of the shell forming wall section I2 is covered by a wire screen I5.

Within the upper portion Y of the shell is 50 mounted a round hollowed case I1 arranged concentrically in the shell and spaced from the annular wall I2. The case is secured to the top plate I3 by means of screws I8 and is formed to provide an enclosed chamber having an upper 55 circular form in communication with a lower of the exterior shell, below the case I'I, as illusconcave recess of decreased,diameter. the.

' -annular wall portion .of` the case ,Il are uprovided one or more apertures I9, which provide air jets from the atmosphere within the vehicle body playing on blades of a wheel to be described later, as shown to advantage at Figure 6. Within the centre of the case I1 is formed an axial tubular bearing 20 in which is journalled a shaft 2| assuming a vertical position in the normal mounting of the ventilator. 10

In the upper portion of the case I1 is mounted a wheel 23 formed with radial projections at the periphery bent to form blades 24, right angular in cross section. The centre of the wheel 23 is fastened to the upper end of the shaft 2l. 15 To the lower depending end of the shaft is fastened a fan wheel 26 embodying a plurality of radial blades preferably turned at an angle in order to effect a suction action during operation. This fan` is mounted in the lower portion trated at Figure 4.

A pipe 21 extends through a radial bore in the annular wall I2 and connects with a bore 28 in the wall of the case I'I communicating with the 25 concave lower portion of the chamber. One end of a tube 29, of rubber or the like, is connected to the outwardly projecting end portion of the pipe 21, the opposite end being connected to a suction apparatus, as for instance the intake 30 manifold of a vehicle motor.

A plurality of outlet tubes 3I, in the present instance two, connect with bores 32 in the annular wall I2 and extend so that the opposite ends of the tubes open to the atmosphere. l 35 As shown in the drawing, the apparatus may be advantageously installed in a car by fastening the top plate I3 to cross bars at the top and disposing the bottom opening of the shell in registration with a corresponding opening in the lining. The tube 29 may be Yextended forwardly and connected with the intake manifold of the vehicle motor. When the motor is in operation, the suction effected in the tube 29 exhausts the air from the concave depression in the lower portion of the case I1 and causes a vacuum to exist therein. Due to said vacuum, atmospheric air from the vehicle body enters the case through the apertures I9 in the form of jets having great velocity and which, impinging on blades 24, produce rotation of the driving wheel 23 fixed on the vertical shaft 2|. This action of the drivingV wheel produces corresponding rotary movement of the fan 26 fixed to the lower end of the shaft so that the foul or stagnant airwithin the vehicle body is drawn through the fan and expelled through the outlet tubes 3| which may extend to the side window frame for conducting the eX- pelled air to the atmosphere. As a result thereof, a Very eicient circulation of air is maintained within the car, maintaining the air in clean, fresh and healthful condition.

Theloperation of the Ventilating fan may be controlled, during the operation of the motor, through the medium of a control Valve 34 mounted in the suction tube 29 in a position conveniently accessible to the seat of the vehicle operator.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

A ventilator of the character described, coinprising a shell constituted of an annular member closed at the top and having a bottom opening, a case mounted against the closed top of the shell and spaced from the annular member, said case having an upper interior chamber ccncentrically formed therein with a central lower depression of smaller diameter, a driving Wheel rotatably mounted Within the upper case charm ber in close proximity to the walls thereof, a suction conduit having communicative connection with the lower depression of the case for operation of the wheel by suction, the said case having an air inlet aperture formed in the upper portion at the wheel periphery, a fan connected with the driving Wheel below the case and across the shell opening, and outlet conduits connected with the inside of the shell for expelling therefrom air drawn therein by the Wheel-driven fan.
